Product Description
This camera is designed to meet high performance and quality requirements while providing ease of use. · Atmel manages the entire process, from the sensor to the camera. The result is a camera able to work in 12 bits, with dedicated electronics that provide excellent signal to noise ratio. Because of the 100% aperture pixel the sensitivity of the camera is fairly high even in near infrared. The programmable settings let the user work with different integration times, gains and offsets. The external trigger allows the user to synchronize the camera on an external event while the 3-shot color mode allows very high resolution for color image acquisition.

Improvements
The Camelia 8M has been redesigned: · To add new features: · Gain: 928 steps from -5 to 29 dB Offset: 0 to 255 LSB Test pattern: ramps up from 0 to 2298 pixel values on each line Median filter: to remove 1 x 1 and columns defects Reducing power consumption from 8.5W down to 5.5W, using a new front panel and internal heat sink. This lowers the CCD temperature by 5°C thus decreasing the magnitude of "white pixels". Decreasing the typical temporal noise from 2.7 to 2.4 LSB
To improve the electro-optical performances, in particular by:
· · ·
To interface with more standard and more cost effective cables To improve reliability Camelia M1 8M is CE and FCC compliant
What changes for the user? · · · New additional commands for gain, offset and test pattern RS-232 transmission speed increased from 9600 to 19200 bauds for LVDS cameras (9600 bauds for CameraLink cameras) Interface connectors: · DATA & SYNC is a 3M MDR connector with better availability, the same pinout but different mechanic RS-232 is a D-Sub 9 female for full-duplex transmission The power supply connector has a camera standard pinout TTL CONTROL is a new D-Sub 9 male connector avoiding the use of a Y cable
New rear panel (see position of connectors)

The Camelia camera is powered by a single +24V power supply. It is configurable via the serial port of the computer (by using either CommCam software or standard RS-232 communicator as TTY or Hyperterminal) for LSD cameras. Camelia is configurable via the serial communication of CameraLink for CameraLink cameras. It also sends digital video. As Camelia's CCD is a full frame sensor, the user must use either pulsed lighting or a chopper/shutter in front of the camera in order to have only incident lighting on the CCD during integration time. The user must design an electro-optical interface to drive the camera, the shutter/chopper or lighting by using the SHUTTER signal delivered by the camera. If required, the system can send an external trigger or external ITC (integration time control signal) to the camera. The BG38 Filter is essential to have a correct white balance on Color Cameras and for use with standard optics (for achromaticity purpose). Note that the following Elements are not provided by Atmel: · · · · · · · Shutter (LCD or Mechanical) BG38 (Anti-infra Red) Filter Control Box Lens Light Source +24V Power Supply Computer
For a complete explanation of the utility of the BG38 Filter and the Shutter, please consult the associated FAQ and the sample images on the Atmel's "Camera Documentation & Software" CD-Rom.

The readout register is along the small side of the image area (vertical image).
Pixel Geometry
Pixels are 10 µm x 10 µm with an aperture ratio of 100%.
Antiblooming by Clocking
Antiblooming can be activated or inhibited (see "Serial Communication" on page 12): · · · Antiblooming OFF: antiblooming inhibited. This position is recommended if antiblooming is not required for the application. Antiblooming ON: antiblooming activated. When binning is disabled, the antiblooming is typically efficient up to 8 times saturation light.
